Here are my two animals who are mentioned in various songs for their nature for being AB/DL. the squirrel is my plushie that i sleep with, and i said under his character description he always has his pink diaper and sock diaper on 99% of the time. the Raccoon is me, just because i find animals in diapers cute.
